<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">BBC<span style="color: black;">期盼</span>micro:bit<span style="color: black;">能够</span>作为编程<span style="color: black;">基本</span>学习的跳板，让学生<span style="color: black;">把握</span>编程知识后<span style="color: black;">能够</span>进一步<span style="color: black;">运用</span>更<span style="color: black;">繁杂</span>的设备，例如Arduino、Raspberry Pi（树莓派）等，<span style="color: black;">因此</span>说micro:bit并非取代Arduino和Raspberry Pi（树莓派），反而是Arduino的<span style="color: black;">基本</span>延伸。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">micro:bit很小，<span style="color: black;">仅有</span>卡片<span style="color: black;">体积</span>（5cm X 4cm），但板载的电子模块还是非常丰富的：5x5 LED<span style="color: black;">表示</span>屏，两颗可编程按键，加速度计，电子罗盘，温度光线传感器，低功耗蓝牙等。</span></p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">按下按键B时，新的当前运行时间会减去start记录的值，<span style="color: black;">这般</span>便得到了从秒表<span style="color: black;">起始</span>计时到当前过了多少时间。此差值将被累加到总时间中，总时间存储在一个名为time的变量中。</span></p>
